Immobilized oxo-vanadium(IV) complex on MNP as recyclable nanocatalyst for the oxidation of sulfides

Today, one of the major concerns of the global vision of world economy is the ability to meet the challenges of energy and sustainability. Catalysts can help in meeting these challenges through to develop greener synthetic routes to produce industrially important organic chemicals [1]. A stable heterogeneous catalyst is proving to be an excellent green catalyst; heterogeneous catalysts have many advantages such as reusability and ease to purify the product [2]. In this regard, the immobilisation of homogeneous catalysts onto magnetic nanoparticles for prepare heterogeneous catalysts have been one of interesting subjects of scientific study because of their interesting properties, including high readily available, high surface area, high dispersion and reactivity with a high degree of chemical stability. A further advantage for these nanoparticles, is that can be efficiently isolated from the reaction mixture through a simple magnetic separation [3-5]. It is clear that green chemistry not only requires the use of green catalyst but also development of solvent-free reactions is one of the most important research threads in green chemistry. Solvent-free conditions have advantages, such as simple reactors, easy work-up procedures, short reaction times and environmentally benignancy [6-7] The selective oxidation of organic molecules is fundamentally in life science and greatly useful in industry [8]. Selective oxidation of sulfides to sulfoxide and sulfone under adjusted reaction conditions is an important process in decontaminate sulfur mustard because of their intensive applications as synthetic intermediates for the construction of various chemically and biologically active molecules and drug metabolism [9]. Some of biologically active sulfoxides play an important role as the rapeutic agents such as antifungal, antihypertensive, anti-atherosclerotic, antibacterial and anti-atherosclerotic as well as psychotropics and vasodilators [10].
